The JBL C25AV-LS is a specialized compact loudspeaker engineered explicitly for life safety and emergency voice evacuation systems, designed to perform reliably in both indoor and outdoor environments. As a critical component of a compliant public address system, its primary function is to deliver intelligible voice announcements and alert tones with absolute reliability under a wide range of conditions. The loudspeaker is constructed to meet rigorous standards for durability and weather resistance, featuring a robust enclosure and components that can withstand moisture, humidity, UV exposure, and temperature extremes. This makes it suitable for installation in a variety of challenging locations, including building exteriors, parking garages, stadium concourses, airport terminals, and industrial facilities where clear, authoritative audio is essential for safety communication.

The design prioritizes voice intelligibility and consistent dispersion, utilizing a high-excursion polypropylene woofer and a balanced-dome tweeter configured to optimize speech frequency reproduction. The loudspeaker's acoustic tuning is focused on the critical midrange frequencies to ensure that emergency instructions and evacuation messages are conveyed with maximum clarity, even in noisy or reverberant spaces. It is available in multiple voltage taps for compatibility with standard 70V/100V constant-voltage amplifier systems, allowing for easy integration into large-scale, multi-zone life safety networks. The inclusion of a multi-wattage tap selector provides installers with the flexibility to balance output levels across a zone for uniform sound pressure coverage, a key requirement in emergency audio design.

Built for longevity with minimal maintenance, the enclosure is constructed from UV-stabilized, high-impact polypropylene and features a corrosion-resistant, powder-coated steel grille. The design incorporates a sealed, gasketed rear chamber to protect the internal components from environmental ingress, ensuring reliable operation in damp or dusty conditions. The loudspeaker is typically supplied with a variety of mounting hardware options for surface, pendant, or wall installation. By combining focused acoustic performance for voice, robust environmental protection, and the necessary regulatory design considerations, the JBL C25AV-LS provides a dependable, code-compliant audio solution dedicated to protecting life and property through clear, reliable sound.
